As mentioned above：part 1 5. Type of sensor used Several types of sensors are used to transfer data to the irrigation multi-controller unit. Each cell is dedicated to capturing and transferring specific data. The first unit is the Soil Moisture sensor (or SMS), which checks the dielectric constant of the soil surface to estimate the volume water content of the surface. The humidity level is proportional to the dielectric constant reading. An SMS controller can be “On demand” (with…
